I dont like any pixelated entity.
I will assume all of them are putting up a fake face and attitude in the game unless i know them in RL.
Hence my Fav person is Niwa.
He is lazy he is fat, but with a kind heart and a smile that will cheers you up, he never look down on people and even spend time teaching me how to trade in game after i attempted to scam him.
Without him i would have quitted 6 year ago.
